Abstract (en)
[origin: US4842076A] A potato harvester comprises a screening conveyor belt following a lifting device, an elevator disposed after the screening conveyor belt, a haulm separating device and a stone separating device. The elevator is formed from a double conveyor having an internally rotating bar-type conveyor belt with narrow openings and an externally rotating bar-type conveyor belt with wide openings. The two conveyor belts rotate in the same direction and are guided parallel to one another at least in the region of the conveying run of the elevator. One bar-type conveyor belt is further equipped with transversely directed entrainment webs which divide the gap between the conveying runs of the two conveyors into conveying compartments.
